if u wanna see what u can get out of ur car col, but dont want full time cage and harness etc. get a half cage (so u can remove it) get bucket seat that can accept harness, and get a harness, and just put them in when u go to the drags. therefore u dont have to get ur car re-registered as a 2 seater (u would if u kept the cage and bucket seat in) however, u can get adr/street legal racing harnesses and reclining bucket seats.
